[0014]
As shown in FIGS. 1, 3 and 4, the circulation unit 3 is constructed by incorporating a circulation fan 16 and a far-infrared heater 17 as a heating means in a heat resistant box 15. A series of air passages 20 with two upper and lower opening ends 18, 19 facing the front surface are defined in the box 15, and an air flow from the upper opening end 18 to the lower opening end 19 is passed through the air passage 20. A circulating blower 16 to be formed is provided. The far-infrared heater 17 is attached in the form of crossing the air passage 20 in the vicinity of the opening end 19 of the air passage 20 on the downstream side of the circulating blower 16. On the back side of the box 15, an air passage structure 22 is provided on both sides, which is opened indoors by a notch window 21 and opened at the back. An engaging member 23 that can be engaged with the retaining structure 10 of the ventilation unit 2 is provided at the upper part on the back side of the box 15, and a fixing edge 24 that can overlap the fixing part 11 of the ventilation unit 2 from the outside is provided as a fixing structure at the lower part. Each is provided. As shown in FIG. 5, several long holes 25 are formed on the fixed edge 24 in the horizontal direction with a linear interval. It can be screwed.
[0015]
In this blower, a wind tunnel 5 of a ventilation unit 2 is inserted through a through-hole 4 provided in a wall 1 of a bathroom or the like with the opening / closing shutter 12 side inward, and a mounting flange 9 is placed against a wall surface on the indoor side, and a mounting screw Then, the circulation unit 3 is attached to the front surface of the ventilation unit 2 so as to cover the attachment flange 9. As for the electrical system, by connecting the system on the ventilation unit 2 side to the system on the circulation unit 3 side, power can be supplied to the circulation blower 16, the far infrared heater 17 and the blower 6, and the circulation unit 3 side as a single blower The operation is controlled by the control circuit 27 provided in (see FIG. 6).
[0016]
When the circulation unit 3 is attached to the ventilation unit 2 and there is an obstacle such as a lighting fixture on the side of the wall surface of the attachment location, the engagement position of the engagement member 23 with respect to the latching structure 10 of the ventilation unit 2 is set in the lateral direction. By sliding, interference with obstacles can be avoided. Moreover, when attaching to the wall surface of the corners, such as a bathroom, the side surface of the circulation unit 3 can be separated from the wall surface by the same operation.
[0017]
When the installation space is to be a dry atmosphere, the blower 6 of the ventilation unit 2, the circulation fan 16 of the circulation unit 3, and the far infrared heater 17 are operated. As a result, the installation space becomes a dry atmosphere due to the circulation of warm air by the circulation unit 3 and the exclusion of humidity by the ventilation by the ventilation unit 2. The intake of the room air into the ventilation unit 2 is performed by the air passage structure 22 that leads to the notch windows 21 on both sides of the circulation unit 3, and the lower surface and the upper surface of the circulation unit 3 hit the wall surface so that there is no gap so that the appearance is good. It is. Since both the suction and blowing of the indoor air of the circulation unit 3 are performed on the front surface of the box 15, the suction performance does not deteriorate even when installed near the ceiling, and there are few restrictions on the installation location.
[0018]
Only the circulation unit 3 can be operated to make the room have a heating atmosphere. However, since the heating is performed by the radiant heat of the far infrared heater 17 and hot air, there is almost no cold air feeling when a person is bathing. The feeling of use as a heating device is also good. If only the ventilation unit 2 is operated, the air in the room can be exhausted and ventilated.
[0019]
Thus, this air blower can be installed using the through-hole 4 of the wall 1 without duct piping etc., and can be easily installed in a new house or an existing house. As a dry ventilation device, the circulation unit 3 and the ventilation unit 2 may not be configured independently but may be configured integrally. However, by adopting the independent configuration, the circulation unit 3 is not only easy to handle but easy to install. 3 can also be attached to the wall surface of a bathroom or the like by using a fixed structure.
[0020]
Even if the existing bathroom is already equipped with ventilation equipment such as a ventilation fan and is functioning effectively, it does not compete with the existing ventilation equipment, and it does not become excessive equipment for ventilation. Heating can be performed. In this sense, it is possible to provide a blower that can be configured to have a dry ventilation atmosphere or a heating atmosphere by using the circulation unit 3 alone in combination with ventilation equipment.
[0021]
In addition, by preparing a box having a simple ventilation function in common with the ventilation unit 2, that is, a decorative grill 28 as shown in FIG. 7, the circulation unit can be used at a time when drying or heating is not required. 3 can be used as a ventilation device exclusively for ventilation by attaching a decorative grille 28 having a small protrusion size and a good appearance. By adopting such a configuration, the circulation unit 3 can be stored when not needed, and the aesthetics and function of the circulation unit 3 can be maintained for a long time, and convenience is enhanced.
